Phosphate ester derivatives of homocamptothecin: Synthesis, solution stabilities and antitumor activities

Homocamptothecins (hCPTs) represents a new promising class of topoisomerase I inhibitors with enhanced stability and superior antitumor activity. Some phosphodiesters and phosphotriesters homocamptothecin derivatives were designed and synthesized based on our previous synthetic route. The cytotoxicity in vitro on three cancer cell lines and antitumor activity in vivo, and inhibitory properties of topoisomerase I of these derivatives were evaluated. Among them compounds 24e and 24f exhibited higher cytotoxic activity than IRT and the former exhibited the best antitumor activity in vivo and solution stability both at pH 7.4 and pH 3.0.

Process for the preparation of tetrahydroindolizines

Described is a process for the preparation of Compound (7) in accordance with the following reaction scheme by reacting Compound (5) with ethylene glycol in a solvent in the presence of a Lewis acid, thereby obtaining Compound (6), and then reacting the resulting compound with a carbonate diester in a solvent in the presence of a metal alkoxide (R1, R6each represents a C1-6alkyl group or the like and R5represents H or C1-5alkyl group). Compound (7) so obtained is useful as an intermediate for camptothecins useful as antitumor agents.

Plant antitumor agents: Synthesis and biological activity of camptothecin analogues

Four analogues, 10-methoxy (20), 12-aza (29), benz[j] (36), and 18-methoxy (38), of camptothecin were obtained by total synthesis. The two water-soluble analogues, 10-[(carboxymethyl)oxy] (24) and 10-[2'-(diethylamino)-ethoxy]-20(S)-camptothecin (26), wit
